This application claims priority under 35 U.S.C § 119(a) to and the benefit of Chinese Patent Application No.202411089003.7, filed on Aug. 8, 2024, the entire disclosure of which is incorporated herein by reference.

The present application relates to the technical field of electronic atomization, and more particularly, to an aerosol generating device.

An aerosol generating device is an electronic device capable of atomizing an atomizing liquid into an aerosol for suction by a user. More specifically, an airflow channel is provided in the aerosol generating device, and an atomizer for atomizing the atomizing liquid is provided in the airflow channel. When the aerosol generating device is sucked by the user, external air flows into the airflow channel from an air inlet of the airflow channel, and flows out of an air outlet of the airflow channel and flows into the user's mouth after mixing with the aerosol generated by the atomization at the atomizer.

In the related art, in order to facilitate the user to regulate an air intake amount according to the user's needs, the aerosol generating device is provided with an air regulating mechanism at the air inlet of the airflow channel. The air regulating mechanism can realize the stepless regulation of the air intake amount at the air inlet to meet a user's need.

Some existing aerosol generating devices are provided with different use modes (e.g., a mouth suction mode, a pulmonary suction mode, and the like). Each use mode needs to be adapted to an accurate air intake amount to achieve an optimal experience effect. However, the existing air regulating mechanism is basically stepless regulation, and a user is difficult to enable himself to regulate the device to an accurate position, so that the optimal experience effect in a certain use mode cannot be experienced by the user.

An aerosol generating device according to embodiments of the present application includes a body in which an airflow channel is provided, wherein the airflow channel comprises an air inlet; and an air regulating assembly movably mounted at the air inlet, wherein the air regulating assembly is provided with a plurality of vent holes, the plurality of vent holes are different in size, the air regulating assembly is capable of moving relative to the body such that one of the plurality of vent holes communicates with the air inlet; and the airflow channel is configured to communicate with an exterior of the body through the vent hole and the air inlet when the vent hole communicates with the air inlet.

The realization of the purpose, functional character and advantages of this application will be further described in conjunction with the embodiments with reference to the accompanying drawings.

The technical solution in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings. It will be apparent that the described embodiments are only some of the embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without involving any inventive effort are within the scope of the present application.

1 FIG. 100 100 10 20 As shown in, in order to solve a problem that an air regulating mechanism of a conventional aerosol generating device cannot perform fine air regulating, in the present application, it is provided an aerosol generating device. The aerosol generating deviceincludes a bodyand an air regulating assembly.

1 FIG. 11 10 11 111 10 14 14 14 141 15 15 14 11 15 11 As shown in, an airflow channelis provided in the body, and the airflow channelincludes an air inlet. Specifically, in the present embodiment, the bodyincludes a housing, an air guide assembly, an atomizing assembly, a liquid supply assembly, and a power supply assembly. The housingprovides installation space and protection for other assemblies. The housingis provided with a suction nozzle. The air guide assembly includes an air guide tube. The air guide tubeis mounted in the housing. A part of the airflow channelis formed in the air guide tube, and other parts of the airflow channelmay be formed by gaps between the assemblies. The specific forming manner may be realized according to the related prior art.

11 10 111 11 141 115 10 111 11 11 115 115 A portion of the airflow channelwhich is at the lower end of the bodyforms the air inlet, and a portion of the airflow channelwhich is at the suction nozzleforms an air outlet. During suction of the user, the air outside the bodyflows from the air inletinto the airflow channel, then flows along the airflow channelto the air outlet, and finally flows out from the air outletand into the user's mouth.

11 13 13 13 13 13 13 The atomizing assembly is mounted in the airflow channel. The atomizing assembly may include heating elements, liquid absorbent cotton, electrical conductors. The heating elementsare electrically connected to the power supply assembly by electrical conductors, so that the heating elementscan be powered on to generate heat. The liquid absorbent cotton is typically sleeved outside the heating element, and the liquid absorbent cotton is used to absorb the atomizing liquid from the liquid supply assembly and to direct the atomizing liquid to the heating element, so that the heating elementin a heating state can atomize the atomizing liquid.

16 16 As described above, the liquid supply assembly is mainly used for supplying the atomizing liquid to the atomizing assembly, and may include a liquid cup. A liquid storage chamber is provided in the liquid cup. The liquid storage chamber stores the atomizing liquid, and a liquid outlet may be provided at a portion of the side wall of the liquid storage chamber which corresponds to the liquid absorbent cotton. So, the liquid absorbent cotton in the atomizing assembly can adsorb the atomizing liquid to the heating elements.

17 17 The power supply assembly generally includes a battery, and a control board. The control board is electrically connected to the battery, and the atomizing assembly is electrically connected to the control board via electrical conductors, so that the atomizing assembly can be controlled to operate or not operate by the control board.

10 100 10 10 11 111 10 11 115 11 115 In conclusion, in the present application, the bodycan realize the basic function of the aerosol generating device. Without adding other components, the user can directly suck the body. At the time of suck, air outside the bodyflows into the airflow channelfrom the air inletat the lower end of the body, while the atomizing assembly atomizes the atomizing liquid into an aerosol. Further, the air flows along the airflow channelto the atomizing assembly and then mixes with the aerosol, then continues to flow to the air outletalong the airflow channel, and finally flows out from the air outletand into the user's mouth.

1 FIG. 100 20 111 20 21 21 20 10 21 111 21 111 11 10 21 111 In the present application, as shown in, the aerosol generating devicefurther includes an air regulating assemblymovably mounted at the air inlet. The air regulating assemblyis provided with a plurality of vent holes. The plurality of vent holesare arranged differently in size. The air regulating assemblyis capable of moving relative to the body, so that one of the vent holescommunicates with the air inlet. When the vent holecommunicates with the air inlet, the airflow channelcommunicates with the outside of the bodythrough the vent holeand the air inlet.

20 115 10 20 10 21 21 111 Specifically, the specific composition of the air regulating assemblymay be flexibly provided according to actual conditions. For example, when the air outletis located at a lower end of a circumferential side surface of the body, the air regulating assemblymay include an air regulating ring. The air regulating ring is rotatably sleeved on the circumferential side surface of the body. Multiple vent holesare penetrated through the air regulating ring. The air regulating ring is rotated so that any one of the vent holesis in corresponding communication with the air inlet.

115 10 20 10 21 21 111 For another example, when the air outletis located on the lower end surface of the body, the air regulating assemblymay include an air regulating rotation disc. The air regulating rotation disc is rotatably mounted on the lower end surface of the body. The multiple vent holesare penetrated through the air regulating rotation disc. The air regulating rotation disc is rotated so that any one of the vent holesis in corresponding communication with the air inlet.

2 FIG. 4 FIG. 115 10 20 23 10 21 211 212 23 23 21 111 For another example, as shown inor, when the air outletis located on the lower end surface of the body, the air regulating assemblymay include a slide blockslidably mounted on the lower end surface of the body. The vent holes(including a first vent holeand a second vent hole) are penetrated through the slide block. The slide blockis slidable, so that any one of the vent holesis in communication with the air inlet.

21 111 11 10 10 111 10 11 111 21 After the vent holecommunicates with the air inlet, the airflow channelin the bodycommunicates with the outside of the bodythrough the air inletand the vent hole, so that the air outside the bodycan flow into the airflow channelthrough the air inletand the vent hole.

21 21 111 111 21 111 20 10 In the present embodiments, since the sizes of the multiple vent holesare provided differently, when different vent holesare in corresponding communication with the air inletin a single one vent hole manner, the air intake amount at the air inletis also different. Therefore, when the different vent holesare in communication with the air inletin a single one vent hole manner by driving the air regulating assemblyto move relative to the body, the air regulating function is realized.

21 111 111 21 111 21 21 111 21 111 111 21 111 21 It should be noted that, in order to ensure that the different vent holesare in corresponding communication with the air inletin the single one vent hole manner to realize the air regulating function (the regulation of the air intake amount), the air inletneeds to be greater than all the vent holes; or the air inletneeds to be greater than or equal to a maximum one of the vent holes. The above-mentioned sentence “the vent holeis in communication with the air inlet” means that the projection of the vent holeon the air inletis completely located within the air inlet. That is, the vent holeis completely in communication with the air inlet, and the air intake amount is determined by the size of the vent hole.

21 21 20 10 100 21 It should also be noted that the size of the vent holeis constant, and the size of the vent holeitself does not change when the air regulating assemblyis moved relative to the body. Therefore, the aerosol generating deviceis configured to have multiple use modes, and each mode needs to be adapted to an accurate air intake amount to achieve an optimal experience effect. In this case, the multiple vent holescan be correspondingly implemented in one use mode.

21 21 100 Specifically, at the time of production, the specific size (i.e., an opening area) of each vent holemay be determined by calculation, test, or the like, so that the ventilation amount of each vent holecorresponds to one use mode of the aerosol generating device.

20 10 21 111 11 21 100 21 100 When the air regulation is required, the user can drive the air regulating assemblyto move relative to the body, so that one of the vent holesis in corresponding communication with the air inletof the airflow channel. The size of each of the vent holesat the time of production corresponds to a certain use mode of the aerosol generating device, and the size of the vent holeis unchanged during air regulation. So, the user can accurately regulate the air intake amount required in a certain use mode, thereby achieving accurate air regulation, and ensuring that the user can experience the best experience effect in a certain use mode of the aerosol generating device.

100 21 211 212 211 212 211 111 212 111 For example, optionally, in one embodiment, the aerosol generating deviceis configured to have a first use mode and a second use mode. The multiple vent holesinclude a first vent holeand a second vent hole. The first vent holeis larger than the second vent hole. The first vent holeis configured to communicate with the air inletin the first use mode. The second vent holeis configured to communicate with the air inletin the second use mode.

Specifically, in the present embodiment, the first use mode is a pulmonary suction mode, and the second use mode is a mouth suction mode. The pulmonary suction mode means that the user sucks the aerosol to enable the aerosol to enter into the lung; and the mouth suction mode means that the user sucks the aerosol to enable the aerosol to stay in the mouth. The ventilation amount required for the pulmonary suction mode is greater than the ventilation amount required for the mouth suction mode.

211 212 211 212 211 111 212 111 In the present embodiments, the size of the first vent holecorresponds to the setting of the pulmonary suction mode, and the size of the second vent holecorresponds to the setting of the mouth suction mode. The first vent holeis larger than the second vent hole. The first vent holeis used to communicate with the air inletin the pulmonary suction mode (that is, the first use mode), and the second vent holeis used to communicate with the air inletin the mouth suction mode (that is, the second use mode). So, the user can accurately regulate the air intake amount required in the pulmonary suction mode or the mouth suction mode, so that the user can experience an optimal pulmonary suction effect or an optimal mouth suction effect.

100 11 10 211 212 211 212 211 212 It should be noted that, based on different types of the aerosol generating devices, the sizes of the airflow channelsin the bodiesare also different, and sizes of the first vent holesand the second vent holesare also different. In practical application, the sizes of both the first vent holeand the second vent holecan be determined by calculation, simulation, test, or the like. So, the ventilation amount of the first vent holecorresponds accurately to the ventilation amount required for achieving the optimal effect in the pulmonary suction mode, and the ventilation amount of the second vent holecorresponds accurately to the ventilation amount required for achieving the optimal effect in the mouth suction mode.

20 211 212 111 20 10 211 212 20 10 111 211 212 20 211 212 20 111 20 10 20 211 212 111 4 FIG. In addition, the air regulating assemblymay make the first vent holeor the second vent holecommunicate with the air inletby rotating, sliding, etc. Alternatively, in one embodiment, as shown in, the air regulating assemblyis slidably mounted to the body, and the first vent holeand the second vent holeare provided at intervals along a sliding direction of the air regulating assembly. Specifically, the bodyand the air inletare stationary, and the first vent holeand the second vent holeare provided at intervals along the sliding direction of the air regulating assembly, so, the first vent holeand the second vent holeare movable to positions in which the air regulating assemblycommunicates with the air inletwhen the air regulating assemblyslides relative to the body. It will be appreciated that the air regulating assemblyenables the first vent holeor the second vent holein corresponding communication with the air inletin a slidable manner. In this way, it is not only simple in structure, but also easy to disassemble and assemble, and thus easy to operate by the user, thereby improving the use experience.

5 10 FIGS.- 20 10 Alternatively, in one embodiment, as shown in, the air regulating assemblyis configured to be linearly slidable with respect to the bodybetween a first position and a second position.

5 6 FIGS.and 20 211 111 212 111 As shown in, when the air regulating assemblyis in the first position, the first vent holeis in full communication with the air inlet, and the second vent holeis provided in a misalignment (i.e., not in communication at all) with the air inlet, so that the user can experience an optimal pulmonary suction effect.

7 8 FIGS.and 20 212 111 211 111 As shown in, when the air regulating assemblyis in the second position, the second vent holeis in full communication with the air inlet, and the first vent holeis provided in a misalignment (i.e., not in communication at all) with the air inlet, so that the user can experience an optimal mouth suction effect.

9 10 FIGS.and 10 FIG. 8 FIG. 20 211 212 111 20 20 211 111 211 111 212 111 212 20 20 20 212 As shown in, when the air regulating assemblyis positioned between the first position and the second position, the first vent holeand/or the second vent holepartially communicates with the air inlet. Specifically, in a state shown in, the air regulating assemblyis positioned between the first position and the second position, and the air regulating assemblyis closer to the first position. At this time, a portion of the first vent holecommunicates with the air inlet, and another portion of the first vent holedoes not communicate with the air inlet; and the second vent holedoes not communicate with the air inletat all. Thus, at this time, a ventilation area of the second vent holeis smaller than a ventilation area of the air regulating assemblyat the first position, and the ventilation amount of the air inlet is less than the ventilation amount of the air regulating assemblyat the first position. When the air regulating assemblyis moved slowly toward the second position (i.e., the position shown in), the ventilation area of the second vent holeis reduced gradually, and the ventilation amount of the air inlet is also gradually reduced.

20 211 212 111 212 It will be appreciated that when the air regulating assemblygradually approaches the second position and has not yet reached the second position, the ventilation area of the first vent holegradually decreases, and a portion of the second vent holealso starts to communicate with the air inlet. That is, the ventilation area of the second vent holegradually increases.

20 111 That is, when the air regulating assemblyis moved between the first position and the second position, the ventilation amount of the air inletis gradually increased or decreased, so that the stepless regulation of the air intake amount is realized.

100 Therefore, in the present application, the aerosol generating devicecan realize the stepless regulation of the airflow amount on the basis of realizing precise regulation of the airflow amount, and thus the air regulation function is more comprehensive.

20 10 20 20 It should be noted that, in order to enable the air regulating assemblyto be more accurately positioned at the first position and the second position, a positioning structure, such as a positioning baffle or a positioning post, may be provided on the body. When the air regulating assemblyabuts against the positioning structure, it can be determined that the air regulating assemblyis at the first position or the second position.

3 5 7 FIGS.,, and 100 30 30 10 30 10 30 10 30 31 31 311 312 20 Alternatively, in another embodiment, referring to, the aerosol generating devicefurther includes a cover. The coveris fixedly connected to the body. Specifically, the coveris covered at the lower end of the body, and the covercan be fixed to the bodyby snapping, screwing, bonding, integral molding, or the like. Furthermore, in the present embodiment, the coveris provided with a positioning through hole. The positioning through holeincludes a first positioning endand a second positioning endopposite to each other in the sliding direction of the air regulating assembly.

6 FIG. 8 FIG. 5 FIG. 7 FIG. 20 10 30 20 22 31 20 22 311 20 22 312 As shown inor, the air regulating assemblyis slidably mounted between the bodyand the cover, and the air regulating assemblyis provided with a toggle buttonpenetrating through and disposing in the positioning through hole. As shown in, when the air regulating assemblyis in the first position, the toggle buttonabuts against the first positioning end. When the air regulating assemblyis in the second position, the toggle buttonabuts against the second positioning end, as shown in.

22 20 10 22 311 22 311 20 22 312 22 312 20 Specifically, in use, the user can manually push the toggle buttonso that the air regulating assemblyslides relative to the body. When the toggle buttonis pushed to the first positioning endand the toggle buttonabuts against the first positioning end, it can be determined that the air regulating assemblyis in the first position. When the toggle buttonis pushed to the second positioning end, and the toggle buttonabuts against the second positioning end, it can be determined that the air regulating assemblyis in the second position.

20 30 20 20 30 20 20 It will be appreciated that, in the present embodiment, the structure for positioning the air regulating assemblyis provided on the cover, so it can conveniently determine whether the air regulating assemblyis in the first position or the second position. The protection of the air regulating assemblycan be realized by the cover. In this way, the occurrence of collision between the external objects and the air regulating assemblymay be avoided to further cause the air regulating assemblyto fall off.

31 31 111 22 211 212 31 20 211 31 11 111 211 31 20 212 31 11 111 212 31 6 FIG. 8 FIG. 6 FIG. 8 FIG. It should be noted here that, the specific position of the positioning through holemay be flexibly selected as desired. For example, alternatively, in one embodiment, as shown inor, the positioning through holeis disposed opposite the air inlet, and the toggle buttonis disposed between the first vent holeand the second vent hole, as well as penetrated through and disposed in the positioning through hole. As shown in, when the air regulating assemblyis in the first position, the first vent holealso communicates with the positioning through hole. At this time, the airflow channelcommunicates with the external environment through the air inlet, the first vent hole, and the positioning through hole. As shown in, when the air regulating assemblyis in the second position, the second vent holealso communicates with the positioning through hole. At this time, the airflow channelcommunicates with the external environment through the air inlet, the second vent hole, and the positioning through hole.

100 31 111 100 It will be appreciated that, in the present embodiment, it is possible to make the structure of the aerosol generating devicemore compact by arranging the positioning holeand the air inletopposite each other, thereby facilitating the miniaturization design of the aerosol generating device.

31 111 30 111 31 22 31 Of course, in other embodiments, the positioning through holemay not be disposed opposite the air inlet. For example, a portion of the covercorresponding to the air inletmay be arranged with a vent through hole. The positioning through holeis located at a side of the vent through hole, and the toggle buttonis penetrated through and disposed in the positioning through hole.

2 4 FIGS.and 10 12 111 20 23 211 212 24 23 24 111 12 Alternatively, in one embodiment, referring to, the bodyincludes a rackhaving an air inlet. The air regulating assemblyincludes a slide blockthrough which a first vent holeand a second vent holeare penetrated. A snap fitteris provided on the slide block. The snap fitterpenetrates through the air inletand is slidably snap-engaged with the rack.

12 10 17 111 12 30 20 23 211 212 23 23 24 23 24 24 24 12 111 20 10 20 10 Specifically, in the present embodiment, the rackis located at the lower end of the body. The rack is used to support a power supply assembly (including a battery, a control board, and the like). The air inletis penetrated through a plate of the rackwhich faces towards the cover. The air regulating assemblyincludes the slide blockhaving an overall shape approximately rectangular parallelepiped. A first vent holeand a second vent holeare penetrated through the slide block. The slide blockis also provided with a snap fitter, which can be integrally formed with the slide block. The number of snap fittersmay be multiple. For example, two snap fitterscan be provided. The two snap fittersare slidably snapped to the rackafter passing through the air inlet. In this way, not only the connection of the air regulating assemblyto the bodycan be realized, but also the air regulating assemblycan be slid relative to the body. So, the structure is simple, and the production is also facilitative.

2 4 FIGS.and 20 25 23 25 23 25 23 12 23 12 251 252 25 251 211 252 212 Alternatively, in one embodiment, as shown in, the air regulating assemblyfurther includes a sealing blockmounted to the slide block. The sealing blockis slid along with the slide of the slide block. The sealing blockis disposed between the slide blockand the rack. So, a clearance between the slide blockand the rackcan be sealed. In the present embodiment, a first sealing holeand a second sealing holeare further penetrated through the sealing block. The first sealing holeis in corresponding communication with the first vent hole, and the second sealing holeis in corresponding communication with the second vent hole.

25 23 12 25 251 252 251 252 211 212 111 211 212 111 It will be appreciated that the sealing blockis compressed between the slide blockand the rack, the sealing blockhas only the first sealing holeand the second sealing holefor ventilation, and the first sealing holeand the second sealing holeare in corresponding communication with the first vent holeand the second vent hole, respectively. So, it is possible to ensure that the airflow can only flow into the air inletthrough the first vent holeor the second vent hole, so that it can avoid the airflow from other positions into the air inlet, and the accuracy of the airflow amount is ensured, thereby achieving the accurate air regulation.

1 FIG. 11 13 100 13 13 13 Alternatively, in one embodiment, as shown in, the airflow channelis further provided with a plurality of heating elements. The aerosol generating devicefurther includes a control board (not shown) and a control switch (not shown). The plurality of heating elementsand the control switch are electrically connected to the control board, respectively. The control switch is used for controlling the first number of heating elementsto be powered on to generate heat in the first use mode. The control switch is also used for controlling the second number of heating elementsto be powered on to generate heat in the second use mode. The first number is greater than the second number.

11 13 13 Specifically, in the present embodiment, as previously described, the atomizing assembly is provided in the airflow channel. The atomizing assembly includes heating elements. In the present embodiment, the number of the heating elementsare multiple, and may be two, three, four, five, six, and the like.

13 13 100 13 13 The multiple heating elementsare provided in the same manner, and the multiple heating elementsare respectively electrically connected to the control board. The aerosol generating devicefurther includes the control switch. The control switch is electrically connected to the control board. The control switch is used to control whether the control board supplies power to the corresponding heating element. That is, the control switch is used to control whether each heating elementis powered on to generate heat.

13 13 Specifically, in the present embodiment, in the first use mode (i.e., in the pulmonary suction mode), the control switch is used to control the first number of heating elementsto be powered on to generate heat. In the second use mode (i.e., in the mouth suction mode), the control switch controls the second number of heating elementsto be powered on to generate heat.

13 13 The airflow amount required for the pulmonary suction mode is larger than the airflow amount required for the mouth suction mode, more atomized liquid is required when the airflow amount is larger, and only less atomized liquid is required when the airflow amount is smaller. Therefore, in the present embodiment, in a case where the first number is greater than the second number, in the pulmonary suction mode, the control switch controls the larger number of heating elementsto be powered on to generate heat to match the larger airflow amount, so as to avoid overlight mouthfeel; and in the mouth suction mode, the control switch controls the smaller number of heating elementsto be powered on to generate heat to match a smaller airflow amount, so as to avoid the overly strong of mouthfeel.

1 FIG. 13 13 13 For example, as shown in, the number of the heating elementsmay be four. In the pulmonary suction mode, the control switch may control the four heating elementsto be powered on to generate heat, and in the mouth suction mode, the control switch may control the two heating elementsto be powered on to generate heat.

10 13 20 It should be noted that the control switch may be a knob, a button, a toggle button, or the like exposed to the surface of the body; or may be an sensing switch. Different numbers of the heating elementsmay be controlled to be powered on to generate heat by sensing the position of the air regulating assemblyvia the sensing switch.

20 13 It should also be noted that when the user toggles the air regulating assemblybetween the first position and the second position to achieve the stepless air regulation, the user may control any number of the heating elementsto be powered on to generate heat according the needs.

1 FIG. 11 112 113 112 113 111 112 113 13 112 113 13 13 Alternatively, in one embodiment, as shown in, the airflow channelincludes a first sub-channeland a second sub-channel. The first sub-channeland the second sub-channelrespectively communicates with the air inlet. The first sub-channeland the second sub-channelare respectively provided with heating element(s). Specifically, the first sub-channeland the second sub-channelmay be each provided with one heating elementor multiple heating elements.

13 112 113 13 112 113 In the present embodiment, the control switch is configured to control the heating elementsin both the first sub-channeland the second sub-channelto be powered on to generate heat in the first use mode. The control switch is also used to control the heating element(s)in the first sub-channeland/or the second sub-channelto be powered on to generate heat in the second use mode.

13 112 113 13 112 113 13 Specifically, in the present embodiment, two heating elementsare provided in each of the first sub-channeland the second sub-channel. In the first use mode (i.e., the pulmonary suction mode), the control switch controls the heating elementsin both the first sub-channeland the second sub-channelto be powered on to generate heat. That is, the four heating elementsare all powered on to generate heat.

13 112 13 113 13 13 113 13 112 13 112 113 13 In the second use mode (i.e., the mouth suction mode), the control switch may control only one heating element or two heating elementsin the first sub-channelto be powered on to generate heat, and control the two heating elementsin the second sub-channelto not be powered on to generate heat. Alternatively, the control switch may control only one heating elementor the two heating elementsin the second sub-channelto be powered on to generate heat, and control the two heating elementsin the first sub-channelnot to powered on to generate heat. Alternatively, the control switch may also control one heating elementin each of the first sub-channeland the second sub-channelto be powered on to generate heat, i.e., one heating elementin each sub-channel is powered on to generate heat.

20 13 13 112 13 113 13 112 13 113 It should be noted here that when the user toggles the air regulating assemblybetween the first position and the second position to achieve the stepless air regulation, the user may control the three heating elementsto be powered on to generate heat by the control switch. Specifically, two heating elementsin the first sub-channeland one heating elementin the second sub-channelmay be powered on to generate heat; or one heating elementin the first sub-channeland two heating elementsin the second sub-channelmay be powered on to generate heat.

That is, the aerosol generating devicein the present embodiment is of a dual-air-passage structure. The first sub-channeland the second sub-channelrespectively communicate with the air inlet, and the first sub-channeland the second sub-channelare respectively provided with the same number of heating elements. Specifically, four heating elementsare provided in total. In this case, two heating elementsare provided in the first sub-channel, and other two heating elementsare provided in the second sub-channel. The first sub-channelhas the same number of heating elementsas the second sub-channel.

13 112 113 13 112 113 In the present embodiment, the control switch is used to control the same number of heating elementsin each of the first sub-channeland the second sub-channelto be powered on to generate heat in the first use mode. The control switch is also used to control the same number of heating elementsin each of the first sub-channeland the second sub-channelto be powered on to generate heat in the second use mode.

13 13 13 112 13 113 Specifically, above-mentioned four heating elementsare provided as an example. As shown in the foregoing, in the first use mode (i.e., the pulmonary suction mode), the control switch needs to control the four heating elementsto be powered on to generate heat. At this time, the control switch controls all of the two heating elementsin the first sub-channelto be powered on to generate heat, and simultaneously controls all of the two heating elementsin the second sub-channelto be powered on to generate heat.

13 13 112 13 113 In the second use mode (i.e., the mouth suction mode), the control switch needs to control the two heating elementsto be powered on to generate heat. At this time, the control switch controls one heating elementin the first sub-channelto be powered on to generate heat, and controls one heating elementin the second sub-channelto be powered on to generate heat.

13 112 113 It will be appreciated that, in the present embodiment, the same number of heating elementsin each of the first sub-channeland the second sub-channelare controlled to be powered on to generate heat by the control switch regardless of the mode. So, it ensures that the aerosol concentration in the two sub-channels is more uniform, which avoids the aerosol concentration difference between the two sub-channels to be too large so as to affect the mouthfeel.
